(1) a C-I-P of Ser. No. 09/232,539 filed Jan. 18, 1999, which is a continuation of Ser. No. 08/895,952 filed Jul. 17, 1997; and

(2) a C-I-P of Ser. No. 09/249,420 filed Feb. 12, 1999, which is a continuation of International Application No. PCT/JP97/02810 filed Aug. 12, 1997.

BACKGROUND OF THE INVENTION

The present invention relates to a series of new neuraminic acid derivatives which have excellent sialidase inhibitory activity and which are therefore useful for the treatment and prevention of influenza and other viral diseases where the replication of the virus is susceptible to sialidase inhibitors. The invention also provides methods and compositions using these compounds for the treatment or prevention of influenza and similar viral infections, as well as processes for the preparation of these compounds.

The compounds of the present invention have a 2-deoxy-2,3-didehydro-N-acylneuraminic acid structure. Sialic acid is N-acetylneuraminic acid.

The influenza virus, as well as a number of other types of virus, have sialidase on the surface of the virus particles. As one of the processes by which such viruses proliferate, subviruses that have budded on the cell surface dissociate from the cell. Such subviruses are coupled to sialic acid on the cell surface mediated by hemagglutinin of the subvirus surface. Subviruses dissociate from the cell as a result of sialidase on the subvirus surface breaking down the sialic acid, thereby resulting in secondary infection of surrounding cells. Thus, inhibition of sialidase would make it possible to inhibit dissociation of subviruses from the cell surface, thereby preventing secondary infection. Accordingly, a substance that has the effect of inhibiting sialidase is considered to be effective in treating or preventing (but preferably treating) influenza.

A number of compounds having a sialidase inhibitory activity and a 2-deoxy-2,3-didehydro-N-acylneuraminic acid backbone are known from WO91/16320 (equivalent to Japanese Patent Publication (Kokoku) No. Hei 5-507068). Other such compounds are known from WO96/26933. These compounds (described in WO91/16320 (Japanese PCT Application (Kokai) No. Hei 5-507068)) include Compound A (GG-167), represented by the following formula which is being developed as a drug for the treatment of influenza.

We have now discovered a series of new compounds having a 2-deoxy-2,3-didehydro-N-acylneuraminic acid backbone which have excellent sialidase inhibitory activity, which is significantly greater than that of the prior art compounds referred to above, and which can thus be used for the treatment and prevention of influenza and other diseases caused by sialidase-bearing viruses.

BRIEF SUMMARY OF INVENTION

It is, therefore, an object of the present invention to provide a series of novel compounds having sialidase inhibitory activity.

Other objects and advantages of the present invention will become apparent as the description proceeds.

The compounds of the present invention are named on the basis of saccharide terminology, in which the main positions are numbered as shown in the following formula:

The compounds are named as derivatives of the unsaturated sugar non-2-enopyranosoic acid, of formula:

The configurations of the carbon atoms at the 4 to 7 positions are D-galacto, while that of the carbon atom at the 8 position is D-glycero, as can be seen from the following partial formula:

In the compounds of the present invention, where R¹ represents an alkyl group, this may be a straight or branched chain group having from 1 to 4 carbon atoms, and examples of such groups include the methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl and t-butyl groups, of which we prefer the methyl group.

Where R¹ represents a haloalkyl group, the halogen atom may be a fluorine, chlorine, bromine or iodine atom, preferably a fluorine, chlorine or bromine atom, and more preferably a fluorine atom. The alkyl part of this haloalkyl group may be any of the alkyl groups having from 1 to 4 carbon atoms listed above. Specific examples of such haloalkyl groups include the fluoromethyl, difluoromethyl, trifluoromethyl, 1-fluoroethyl, 2-fluoroethyl, 1-fluoropropyl, 2-fluoropropyl, 3-fluoropropyl, 4fluorobutyl, chloromethyl, 1-chloroethyl, 2-chloroethyl, 1-chloropropyl, 2-chloropropyl, 3-chloropropyl, bromomethyl, 1-bromoethyl, 2-bromoethyl, 1-bromopropyl, 2-bromopropyl, and 3-bromopropyl groups, of which we prefer a methyl group substituted with at least one fluorine atom, particularly the fluoromethyl or difluoromethyl groups.

More preferably R¹ represents a methyl group or a halomethyl group, particularly a methyl, fluoromethyl or difluoromethyl group, more preferably a methyl group.

Where R², R³ or R^(a) represents an aliphatic carboxylic acyl group having from 2 to 25 carbon atoms, this may be a straight or branched chain group; and is preferably an alkanoyl (alkylcarbonyl) group having from 2 to 25 carbon atoms. Specific examples of such groups include the acetyl, propionyl, butyryl, isobutyryl, pivaloyl, valeryl, isovaleryl, octanoyl, nonylcarbonyl, decylcarbonyl, 3-methylnonylcarbonyl, 8-methylnonylcarbonyl, 3-ethyloctylcarbonyl, 3,7direthyloctylcarbonyl, undecylcarbonyl, dodecylcarbonyl, tridecylcarbonyl, tetradecylcarbonyl, pentadecylcarbonyl, hexadecylcarbonyl, 1-methylpentadecylcarbonyl, 14methylpentadecylcarbonyl, 13,13-dimethyltetradecylcarbonyl, heptadecylcarbonyl, 15-methylhexadecylcarbonyl, octadecylcarbonyl, 1-methylheptadecylcarbonyl, nonadecylcarbonyl, icosylcarbonyl and tricosylcarbonyl groups. Of these, we prefer those alkylcarbonyl group having from 6 to 25 carbon atoms, more preferably those alkylcarbonyl groups having from 8 to 16 carbon atoms.

R² preferably represents a hydrogen atom or an aliphatic carboxylic acyl group having from 6 to 25 carbon atoms, more preferably an aliphatic carboxylic acyl group having from 8 to 16 carbon atoms, particularly an octanoyl, nonylcarbonyl, undecylcarbonyl, tridecylcarbonyl or pentadecylcarbonyl group.

R³ preferably represents a hydrogen atom or an aliphatic carboxylic acyl group having from 6 to 25 carbon atoms, more preferably a hydrogen atom or an aliphatic carboxylic acyl group having from 8 to 16 carbon atoms, particularly an octanoyl, nonylcarbonyl, undecylcarbonyl, tridecylcarbonyl or pentadecylcarbonyl group.

Still more preferably, R² represents an aliphatic acyl group having from 8 to 16 carbon atoms (particularly an octanoyl, nonylcarbonyl, undecylcarbonyl, tridecylcarbonyl or pentadecylcarbonyl group), and R³ represents a hydrogen atom.

Where X represents a halogen atom, this may be a fluorine, chlorine, bromine or iodine atom, preferably a fluorine, chlorine or bromine atom, and more preferably a fluorine atom;

Where X represents an alkoxy group having from 1 to 4 carbon atoms, this may be a straight or branched chain group, and examples include the methoxy, ethoxy, propoxy, isopropoxy, butoxy, isobutoxy, sec-butoxy and t-butoxy groups, of which we prefer the methoxy and ethoxy groups.

X preferably represents a fluorine atom, or a methoxy or ethoxy group.

Where Y represents a group of formula R^(b)R^(c)N— or R^(b)R^(c)N—O— and R^(b) and/or R^(c) represents an alkyl group having from 1 to 4 carbon atoms, this may be a straight or branched chain group, and examples include the methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl and t-butyl groups, of which we prefer the methyl group. However, we most prefer that at least one, and preferably both, of R^(b) and R^(c) should represent a hydrogen atom. Thus, the preferred group represented by R^(b)R^(c)N—O— is a group of formula NH₂—O—, and the preferred group represented by R^(b)R^(c)N— is NH₂—, i.e. an amino group.

Y preferably represents a group of formula NH₂ or NH₂—O—, more preferably an amino group of formula NH₂.

Z preferably represents an oxygen atom.

The compounds of the present invention contain a carboxy group, and can, therefore, form salts with cations. There is no particular restriction on the nature of these salts, provided that, where the compounds are to be used medically, the salts should be pharmaceutically acceptable, that is they should not be more toxic (or unacceptably more toxic) than the free acid, nor should they be less active (or unacceptably less active) than the free acid. When the compound is to be used for other purposes, for example as intermediates in the preparation of other, and possibly more active compounds, even this restriction does not apply. Examples of such salts include: alkali metal salts, such as the sodium salt, potassium and lithium salts; alkaline earth metal salts, such as the calcium and magnesium salts; other metal salts, such as the aluminum, iron, zinc, copper, nickel and cobalt salts; other inorganic salts, such as the ammonium salt; amine salts, such as the t-octylamine, dibenzylamine, morpholine, glucosamine, phenylglycine alkyl ester, ethylenediamine, methylglucanine, guanidine, diethylamine, triethylamine, dicyclohexylamine, N,N′-dibenzylethylenediamine, chloroprocaine, procaine, diethanolamine, benzyl-phenethylamine, piperazine, tetramethylammonium and tris(hydroxymethyl)aminomethane salts.

Furthermore, when the compound of the present invention contains a guadinino group, it can be also converted to a salt. Such salts, likewise, are not particularly restricted, except that, where they are for medical use, they should be pharmaceutically acceptable. Examples of such salts include: hydrohalides, such as the hydrofluoride, hydrochloride, hydrobromide or hydroiodide; other inorganic acid salts, such as the nitrate, perchlorate, a sulfate or phosphate; lower alkanesulfonates, such as the methanesulfonate, trifluoromethanesulfonate or ethanesulfonate; arylsulfonates, such as the benzenesulfonate or p-toluenesulfonate; organic acid salts, especially carboxylic acid salts, such as the acetate, trifluoroacetate, malate, fumarate, succinate, citrate, tartarate, oxalate or maleate; and amino acid salts, such as the glycine, lysine, arginine, ornithine, glutamic acid salt or aspartic acid salt. Of these, we prefer the alki metal salts, such as the sodium, potassium and lithium salts, organic acid salts, such as the acetate and trifluoroacetate and inorganic acid salts, such as the hydrochloride and sulfate.

Since the compounds of the present invention contain a carboxy group, they can form esters. There is no particular restriction on the nature of these esters, provided that, where the compounds are to be used medically, the esters should be pharmaceutically acceptable, that is they should not be more toxic (or unacceptably more toxic) than the free acid, nor should they be less active (or unacceptably less active) than the free acid. When the compound is to be used for other purposes, for example as intermediates in the preparation of other, and possibly more active compounds, even this restriction does not apply.

The compounds of the present invention may be prepared by a variety of processes well known in the art for the preparation of compounds of this type, for example as illustrated by the following Methods A, B and C.

The compound of formula (2), which is used as a starting material in Method A or B, can be prepared by the following Methods D, E, F or G.

The compound of formula (5), which is used as a starting material in Method C, can be prepared by the following Method H.

Method A

In the above formulae:

R¹, R², R³, X and Z are as defined above;

R^(2a) represents any of the groups or atoms represented by R² or a hydroxy-protecting group, preferably t-butyldimethylsilyl group;

R^(3a) represents any of the groups or atoms represented by R³or a hydroxy-protecting group, preferably t-butyldimethylsilyl group;

X^(a) represents any of the groups or atoms represented by X or a protected hydroxy group, preferably t-butyldimethylsilyloxy group;

W represents a hydrogen atom or an ester residue;

W^(a) represents any of the groups or atoms represented by W or a carboxy-protecting group, preferably an allyl group, a methoxymethyl group, a methylthiomethyl group, a [2-(trimethylsily)ethoxy]methoxy group or a diphenylmethyl group, more preferably a diphenylmethyl group; and

Boc represents a t-butoxycarbonyl group.

In this Method, a compound of formula (1a) is prepared by reacting a compound of formula (2) with N,N′-t-butoxycarbonylthiourea to give a compound of formula (3), which is then deprotected.

Step A1

In this Step, a compound of formula (3) is prepared by reacting the compound of formula (2) with N,N′-di-t-butoxycarbonylthiourea in the presence of a base and mercuric chloride and in an inert solvent.

The reaction is normally and preferably effected in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved and that it can dissolve the reagents, at least to some extent. Examples of suitable solvents include: aromatic hydrocarbons, such as benzene, toluene and xylene; ethers, such as diethyl ether, diisopropyl ether, tetrahydrofuran, dioxane, dimethoxyethane and diethylene glycol dimethyl ether, and amides, such as N,N-dimethylacetamide, and dimethylformamide. Of these, we prefer the amides, particularly N,N-dimethylacetamide or dimethylformamide.

There is likewise no particular restriction on the nature of the bases used, and any base commonly used in reactions of this type may equally be used here. Examples of such bases include: organic bases, such as triethylamine or dimethylaminopyridine.

The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. The preferred reaction temperature will depend upon such factors as the nature of the solvent, and the starting material or reagent used. However, in general, we find it convenient to carry out the reaction at a temperature of from −10 to 50° C., more preferably from 10 to 30° C. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents, base and solvent employed. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 1 hour to 24 hours, more preferably from 5 to 10 hours, will usually suffice.

After completion of the reaction, the desired compound can be obtained by conventional means. For example, one suitable recovery procedure comprises: filtering the reaction solution under reduced pressure to remove the insolubles; adding a water-immiscible organic solvent, such as ethyl acetate, thereto, separating the organic layer containing the desired compound after washing with water; and distilling off the solvent after the organic layer is dried, for example over anhydrous magnesium sulfate.

The desired compound can, if desired, be further purified by recrystallization or by the various forms of chromatography, such as column chromatography or preparative thin layer chromatography.

Step A2

In this Step, a compound of formula (1a), which is a compound of the present invention, is prepared by treating the compound of formula (3) with a reagent which can remove a t-butoxycarbonyl group, in an inert solvent.

The reaction is normally and preferably effected in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved and that it can dissolve the reagents, at least to some extent. Examples of suitable solvents include: alcohols, such as methanol and ethanol; water; or a mixture of any two or more thereof.

There is likewise no particular restriction on the nature of the reagents used to remove the t-butoxycarbonyl group, and any reagent commonly used in reactions of this type may equally be used here. Examples of such reagents include acids, and any acid commonly used as an acid catalyst may be used, for example a Bronsted acid, such as an inorganic acid (e.g. hydrochloric acid, hydrobromic acid, sulfuric acid, perchloric acid or phosphoric acid) or an organic acid (e.g. acetic acid, formic acid, oxalic acid, methanesulfonic acid, p-toluenesulfonic acid, trifluoroacetic acid or trifluoromethanesulfonic acid), preferably an organic acid (particularly acetic acid or trifluoroacetic acid).

The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. The preferred reaction temperature will depend upon such factors as the nature of the solvent, and the starting material or reagent used. However, in general, we find it convenient to carry out the reaction at a temperature of from −10 to 50° C., more preferably from 10 to 30° C. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents and solvent employed. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 15 minutes to 10 hours, more preferably from 1 to 5 hours, will usually suffice.

After completion of the reaction, the desired compound can be recovered from the reaction mixture by conventional means. For example, one suitable recovery procedure comprises: neutralising the reaction solution and purifying the residue obtained by distilling off the solvent under reduced pressure by means of silica gel chromatography.

Where R^(2a) or R^(3a) represents a hydroxy-protecting group, X^(a) represents a protected hydroxy group or W^(a) represents a carboxy-protecting group, a compound of the present invention can be prepared by deprotecting these protecting groups further.

The reaction employed for the removal of the protecting group will vary, depending on the nature of the protecting group. However it can be carried out by conventional means, for example, by the method described in “Protective Groups in Organic Synthesis”, Second Edition (written by, Greene and Wuts, John Wiley & Sons, Inc., published in 1991), the disclosures of which are incorporated herein by reference.

Where the hydroxy-protecting group is a trialkylsilyl group, such as a t-butyldimethylsilyl group, acetic acid in a mixture of water and tetrahydrofuran or tetrabutylammonium fluoride in tetrahydrofuran can preferably be used. Where the carboxy-protecting group is a diphenylmethyl group, catalytic reduction using hydrogen gas and a catalyst such as palladium black in a mixture of methanol and tetrahydrofuran, trifluoroacetic acid in phenol, acetic acid as an acid and a solvent or trifluoroboran-diethyl ether complex in acetic acid can be used.

Method B

In this Method, a compound of formula (1) is prepared by reacting the compound of formula (2) with ammonia or a hydroxylamine which may be substituted by an alkyl group having from 1 to 4 carbon atoms at the amino moiety, if desired, followed by deprotection.

In the above formulae, R¹, R², R³, R^(2a), R^(3a), X, Y, W, Z, X^(a) and W^(a) are as defined above.

Step B1

In this Step, a compound of formula (4) is prepared by reacting the compound of formula (2) with a cyanating agent in an inert solvent.

The reaction is normally and preferably effected in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved and that it can dissolve the reagents, at least to some extent. Examples of suitable solvents include: alcohols, such as methanol ethanol, propanol isopropanol, butanol, isobutanol, t-butanol, isoamyl alcohol, diethylene glycol, glycerin, octanol, cyclohexanol and ethylene glycol monomethyl ether (methyl Cellosolve—“Cellosolve” is a trade mark); amides, such as formamide, dimethylformamide, N,N-dimethylacetamide, N-methyl-2-pyrrolidone, N-methylpyrrolidinone and hexamethylphosphoric triamide and sulfoxides, such as dimethyl sulfoxide and sulfolane. Of these, we prefer the alcohols (particularly methanol).

There is likewise no particular restriction on the nature of the cyanating agents used, and any cyanating agent commonly used in reactions of this type may equally be used here. Examples of such cyanating agents include cyanogen bromide, in which case, sodium acetate is simultaneously used as a base.

The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. The preferred reaction temperature will depend upon such factors as the nature of the solvent, and the starting material or reagent used.

BIOLOGICAL ACTIVITY

The 2-deoxy-2,3-didehydro-N-acylneuraminic acid derivatives of the present invention have excellent sialidase inhibitory activity, and are, accordingly, useful in the prophylaxis and therapy of influenza The activity of compounds of the present invention is further illustrated by the following Experiments.

EXPERIMENT 1 Influenza Virus Replication Inhibitory Activity

Influenza virus strain A/Yamagata/32189(H1N1) was proliferated in a live hen's egg, and the virus produced by this technique was then applied to plates of MDCK cells (derived from canine kidney) to obtain plaques. MDCK cells were infected with virus in the presence or absence of various concentrations of test compound. Influenza virus replication inhibitory activity of test compounds could then be calculated by comparing the amounts of plaques in the control and test samples.

The methodology of the present Experiment was generally in accordance with Antimicrobial Agents And Chemotherapy, 17, pp.865-870 (1980).

More specifically, MDCK cells were cultured to a single, confluent layer on the surface of petri-dishes having a diameter of 35 mm. The culture conditions of the MDCK cells on these plates were 37° C. under a sterile atmosphere containing 5% v/v carbon dioxide gas. After the cells had reached confluence, the culture liquid was sucked off. An amount of phosphate buffered physiological saline solution containing 50-100 pfu (plaque forming units) of virus was then added to the plates.

The resulting plates were then left to stand for 1 hour at 37° C. to permit adsorption of the virus, after which time the remaining phosphate buffered physiological saline solution was sucked off and replaced with MEM medium (Gibco BRL) containing 1 μg/ml of trypsin (Cooper Biomedical), 0.01% w/w DEAE dextran (Pharmacia LKB), 0.6% w/w agar (Sigma) together with an amount of between 0.00056 and 5.6 μg/ml of test compound.

Cultivation of the plates was continued at 37° C. for 40 hours under a sterile atmosphere containing 5% carbon dioxide gas, after which time solidified agar medium was recovered. Crystal violet (Merck) was dissolved in 19% methanol to a final concentration of 0.01% and was added to the recovered agar in order to fix and stain the cells, thereby permitting determination of the number of plaques.

The number of plaques formed in the absence of test compound is taken as 100% (the control). It was then possible to calculate IC₅₀ (the concentration in nM/ml at which the test compound reduces the number of observed plaques to 50%,) as a measure of influenza virus replication inhibitory activity.

The compounds of the present invention were found to exhibit high influenza virus replication inhibitory activity, as shown in Tables 3 and 4, below.

EXPERIMENT 2 Influenza Virus Sialidase Inhibitora Activity

In this experiment, a sample of influenza virus strain A/PR/8/34(H1N1) was dissolved by means of a surfactant, after which the virus membrane fraction was purified by centrifugation. The thus purified fraction was used as a crude influenza virus sialidase, and p-nitrophenyl-N-acetylneuraminic acid (Wako Pure Chemical) was used as a substrate to perform similar tests to those described in Analytical Biochemistry, 94, 287-296 (1979).

An enzyme solution was first prepared such that the final enzyme activity was 0.001 1 units/ml (1 unit corresponds to that amount of enzyme which hydrolyzes 1 μmole of substrate in 1 minute). Also prepared beforehand were aqueous solutions of test compound in various concentrations; an aqueous solution of the substrate to a concentration of 33 μg/ml, and a 20 mM 2-(N-morpholino)-ethanesulfonic acid buffer (pH 6.5) containing 50 mM calcium chloride. These solutions were combined to prepare a mixture having a final volume of 150 μl, and which was then left to stand at 37° C. for 20 minutes. The absorbance of any p-nitrophenol formed in the mixture was measured at 415 nm. The absorbance measured at 415 nm where the mixture was prepared by adding water in place of the aqueous solution of test compound was taken as 100%. Thus, IC₅₀ (nM) was determined as the concentration of the sample at which the absorbance was reduced by 50%, to provide a measure of influenza virus sialidase inhibitory activity.

The results are shown below in Table 5.

EXPERIMENT 3 Mouse Infection Test

A solution of 1500 pfu of mouse-adapted influenza virus strain A/PR/8/34 in 50 μl of a 0.42% v/v bovine serum albuminontaining phosphate buffer was prepared, and mice (BALB/C, female, age: 5 to 6 weeks, 20 g) were infected dropwise, intranasally, with the resulting solution. Test compound was suspended in a physiological saline solution to provide a dosage of 0.9 μmol/kg/50 μl. The resulting suspension was administered dropwise intranasally 3 times in total, once 4 hours before the virus infection, once 4 hours after the infection and once at 17 hours after the infection. The result is shown in terms of the number of mice surviving after 6 days, 8 days, 10 days and 15 days from infection. The test was conducted on groups of mice, each group consisting of 12 animals. The results are shown in Table 6 below.

Thus, it can be seen that the compounds of the present invention greatly enhance the survival rate of animals exposed to the influenza virus.

In the following, each Process will be described in detail.

Process A′ is a process for preparing the compound (1′) of the present invention by eliminating the protecting group of the compound (3′) obtained by reacting the raw material compound (2′) which is easily available according to the method described later with N,N′-di-t-butoxycarbonylthiourea.

(Step A′-1)

The present step is to prepare the compound (3′) by reacting the compound (2′) with N,N′-di-t-butoxycarbonylthiourea in an inert solvent in the presence of a base and mercuric chloride.

The solvent employable is not particularly limited so long as it does not affect the reaction and includes aromatic hydrocarbons such as benzene, toluene and xylene; ethers such as diethyl ether, diisopropyl ether, tetrahydrofuran, dioxane, dimethoxyethane and diethylene glycol dimethyl ether, and amides such as N,N-dimethylacetamide and dimethylformamide, preferably amides (particularly N,N-dimethylacetamide and dimethylformamide).

The base employable here includes preferably organic bases such as triethylamine and dimethylaminopyridine.

The reaction temperature is usually from −10 to 50° C., preferably from 10 to 30° C.

The reaction time varies depending on the material used, the base, the reaction temperature, etc. and is usually from 1 to 24 hours, preferably from 5 to 10 hours.

After the reaction, the desired compound is obtained, for example, by filtering the reaction mixture under reduced pressure to remove insolubles, adding a water-immiscible organic solvent such as ethyl acetate thereto, washing the mixture with water, separating the organic layer containing the desired compound, drying the layer over anhydrous magnesium sulfate, and distilling off the solvent.

If necessary, the desired compound can be further purified by recrystalization or various kinds of chromatographies.

(Step A′-2)

The present step is to prepare the compound (1′) of the present invention by reacting the compound (3′) with a reagent for eliminating the tert-butoxycarbonyl group in an inert solvent.

The solvent employable is not particularly limited so long as it does not affect the reaction and includes preferably alcohols such as methanol and ethanol, water and a mixture thereof.

The reagent for elimination is preferably an acid, and the acid is not particularly limited so long as it is used as an acid catalyst in the usual reaction and includes Bronsted acids such as inorganic acids, e.g. hydrochloric acid, hydrobromic acid, sulfuric acid, perchloric acid and phosphoric acid, and organic acids, e.g. acetic acid, formic acid, oxalic acid, methanesulfonic acid, para-toluenesulfonic acid, trifluoroacetic acid and trifluoromethanesulfonic acid; Lewis acids such as zinc chloride, tin tetrachloride, boron trichloride, boron trriluoride and boron tribromide; and acidic ion exchange resins, preferably organic acids (particularly acetic acid and trifluoroacetic acid).

The reaction temperature is usually from −10 to 50° C., preferably from 10 to 30° C.

The reaction time varies depending on the material, the base, the reaction temperature, etc. and is usually from 15 minutes to 10 hours, preferably from 1 to 5 hours.

After the reaction, the desired compound can be obtained, for example, by neutralizing the reaction mixture, distilling off the solvent under reduced pressure, and then purifying the residue over silica gel column chromatography.

Further, in the case where R^(2a), R^(3a) or R^(4a) is a protecting group of a hydroxyl group or W^(a) is a protecting group of a carboxyl group, they are further eliminated to obtain the compound (1′) of the present invention.

The method for eliminating the protecting group varies depending on the kind of the protecting group and can be carried out according to the methods usually used, for example, the methods described in Protective Groups in Organic Synthesis, Second Edition (1991, Green et al.).

In the case where the protecting group of a hydroxyl group is a trialkylsilyl group such as a tert-butyldimethylsilyl group, acetic acid is preferably used in a mixture of water and tetrahydrofuran, or tetrabutylammonium fluoride is used in tetrahydrofuran.

In the case where the protecting group of a hydroxyl group is an isopropylidene group, the method of Step E′-2 or E′-4 described later is used.

In the case where the protecting group of a carboxyl group is a diphenylmethyl group, catalytic reduction is carried out, an acid such as acetic acid and trifluoroacetic acid is used or trifluoroboran-diethyl ether complex is used.

In the case where the protecting group of a carboxyl group is a benzyl group, catalytic reduction is carried out, and in the case where the protecting group is the methyl group, hydrolysis is carried out.

Process B′ is a process for preparing the compound (1′) of the present invention by reacting the raw material compound (2′), which is easily available according to the method described later, with a cyanating agent, reacting the resulting compound with ammonia, and further, if necessary, eliminating the protecting group.
